假定英语课上老师要求同桌之间交换修改作文,请你修改你同桌写的以下作文。作文中共有10处语言错误,每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。

增加:在缺词处加一个漏字符号(∧),并在其下面写出该加的词。 

删除:把多余的词用斜线〔\〕划掉。

修改:在错的词下划一横线,并在该词下面写出修改后的词。

注意:1.每处错误及其修改均仅限一词;

      2).只允许修改10处,多者(从第11处起)不计分。

    Yesterday our club held an English speech contest, which theme was “Challenge Myself”. A large number of students attended to the contest and showed their wonderful performances. In the stage, though face great pressure, the speakers bravely overcame it and challenged them to achieve great success. Moreover, they impressed us deep with their unusual confidences and performances.

    Through such activity, we know a lot more about our students but we have gained much, such as self-confidence and bravery. Besides, our club was growing stronger.

阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式(不超过3个单词)。

    Once a group of 50 people was attending a seminar. Halfway{#blank#}1{#/blank#} his talk, the speaker stopped and decided{#blank#}2{#/blank#}(create) a group activity. He went around the hall and gave each person a balloon. Each one was asked to write his or her name on the balloon{#blank#}3{#/blank#}(use) a marker pen. Then all the balloons{#blank#}4{#/blank#}(collect) and put in another room.

    The speaker then led the group to the room full of balloons and asked them to find the balloon that had their name{#blank#}5{#/blank#}(write) on within five minutes.  Everyone was{#blank#}6{#/blank#}(hurry) searching for their name, bumping into each other, pushing each other around. It was chaos. At the end of the five minutes no one could find their own balloon.

    Now each person was asked to randomly collect{#blank#}7{#/blank#}balloon and give it to the person whose name was on it. Within two minutes everyone had their own balloon. When everyone quieted down, the speaker began to talk, saying that this is exactly{#blank#}8{#/blank#}was happening in our lives.

    We may like to think of{#blank#}9{#/blank#}(us) more important than others, but our happiness sometimes lies in the happiness of other people. Give them their happiness {#blank#}10{#/blank#}you will get your own happiness.

(19分)如图所示,在铅板A上放一个放射源C可向各个方向射出速率为射线,B为金属网,A、B连接在电路上,电源电动势为,内阻为,滑动变阻器总阻值为,图中滑动变阻器滑片置于中点,A、B间距为d,M为荧光屏(足够大),它紧挨者金属网外侧,已知粒子的质量为,不计射线所形成的电流对电路的影响,求:

(1)闭合开关S后,AB间的场强的大小是多少?
(2)粒子到达金属网B的最长时间?
(3)切断开关S,并撤去金属网B,加上垂直纸面向内、范围足够大的匀强磁场,磁感应强度大小为B,设加上B后粒子仍能到达荧光屏。这时在竖直方向上能观察到荧光屏亮区的长度是多少?
7.
(15分)如图所示的空间,匀强电场的方向竖直向下,场强为,匀强磁场的方向水平向外,磁感应强度为.有两个带电小球A和B都能在垂直于磁场方向的同一竖直平面内做匀速圆周运动(两小球间的库仑力可忽略),运动轨迹如图。已知两个带电小球A和B的质量关系为,轨道半径为

(1)试说明小球A和B带什么电,它们所带的电荷量之比等于多少?
(2)指出小球A和B的绕行方向?
(3)设带电小球A和B在图示位置P处相碰撞,且碰撞后原先在小圆轨道上运动的带电小球B恰好能沿大圆轨道运动,求带电小球A碰撞后所做圆周运动的轨道半径(设碰撞时两个带电小球间电荷量不转移)。
